Mr. John Dolan:

I would say that provision for measurement was allocated to schools through the CO2 monitors, which allowed schools to establish the level of carbon dioxide in a room, which is related to airborne contaminants. There is that provision in all schools. They were centrally distributed from the Department of Education and every school in the country got a number of those monitors. At the last count, more than 40,000 of them had been issued but we can confirm that figure later, if need be.
